PLATE-STAND FOB WIRE-DRAWING.

To d'llivhom it may concern:

Be t known that .1, PETER VANpER- AUWERA, a subject of the King of Belglum,

residing at New Brunswick, in the county of Middlesex and State'fof New Jersey, have 1 invented certain new and useful Improvements in Plate-Stands "for Wire-Drawing,

' of which the following is a specification.

hplo,

My invention relates'to a plate stand for wire drawing,-the object being to provide a stand which will overcome the objectionable features incident to the use of thepresent fixed stand. 1 r In wire drawing it'is customary to use a die plate having numerous holes drilled therein. In practice it is diflicut to form and maintain these holes with absolute ac- V curacy; that is, perpendicular to the face of the plate, so that considerable time is requiredby the operator to cast the wire at the beginning of the drawing; that is, to make the drawn wire have a tendency to assumea' coil of not less diameter than that of the block. The die plate in general use rests in a stand fixed to the bench and unlessthe plateis properly alinedthe wire becomes what is called wavy that is, tends to go If 7 into a coil the diameter ofwhich is less than that of the block. Inbeginning the drawing of a given reel of wire it is necessary for the operator, after drawing the end through one of the die holes and securing it to the block and starting the rotation of the latter, to manipulate: the die plate by hand and'by means'of wedge blocks so adjust it on the" fixed stand that the axis of the die [hole will strike the given point on the circumference of the block where every It is only by longexperience that an operator is able to aline the die plate properly and even then i it requires several minutes and the rotation xof th'elblock twenty or more times before the proper adjustment can be made. This loss of time'isconsiderable in a mill having a large number of blocks and in addition to this loss of time the initial wavy coils or convolutions of thewire give considerable trouble in the subsequent drawings. In fact, I, v

coils.

it is often necessary to scrap these wavy By means of the stand hereafter described I am enabled to aline or ad ust the die plate before the drawing begins by a very Specification of Letters Patent. 7 Application filed. June 30, 1908. Serial No. 44:1,19.

simple operation requiringbut a few seconds of time and by which the first convolution is properly coiled around the block thus avoiding any loss of material. This saving in time and material will be appreciated when it is understood that in some cases as many as ten drawing operations are necessary for piano wire, the class of work to which my invention has been applied in practice, and to begin successive operations with a reel ofwire that has been previously properly drawn throughout its length is of great advantage.

The essential feature of my invention comprises a die stand supported in such manner as to be capable of free movement in every direction so that when the die plate is clamped in position before the drawing operation, or before the insertion of a wire through a die hole, the die plate will remain in fixed relation to the stand and requires no subsequent manipulation relatively there to. In addition to this feature the stand also comprises a guide for the wire capable of adjustment in axial alinement with a given die hole so that upon the insertion of the wire at the beginning of the drawing operation the initial rotation of the block upon which the drawn Wire is coiled will swing the stand and the plate and guide carried thereby into such position that thewire will be properly cast. These and other featuresof the invention will be understood from the following description takenin connection with the accompanying drawings in which- Figure l is a top view of the complete stand; Fig. 2 a vertical longitudinal section on the plane of the line 22 of Fig. 1; Fig. 3 a transverse vertical section on the plane of the line 33 of Fig. 1 looking in the direction of the arrow; Fig. 4 a rear elevation; and Fig. 5 a detail viewof a modification.

Similar numerals of reference indicate similar parts in the several views.

The die plate holder illustrated comprises end pieces 1 and 2 in the form of castings of suitable shape. The former is provided on its inner face with a central recessed boss 1, as indicated in Fig. 2, and its outer face is recessed at three points equidistant from the center of the boss 1. In practice the end piece 1 is cast in the form of a spider with three legs, the recesses l being formed near the outer ends of the legs. piece 2 is formed with a central opening 5 to receive one end of a guide as described hereafter, and with three overhanging brackets or lugs 6 recessed at the points 7 equidistant from the center of the opening 5. The recesses 7 are struck on a circle having the same radius as that on which the recesses 4 in the piece 1 are struck. The pieces 1 and 2 are connected through three straps 8 of equal length, and stirrups 9 secured to the ends of said straps. The stirrups encircle the recessed ends of the forward piece 1 and the overhanging lugs 6 of the piece 2, and are provided with inwardly projecting hardened steel studs 10 which rest in the re cesses 1 and 7. The straps 8 extend within the bodies of the stirrups and are of such length as to prevent the unseating of the studs 10. As shown in Fig. 2, there is a slight play between the straps and the end pieces. One purpose being to permit of a universal movement of the stand and die plate, I support the former at one end by an anchor 11 secured to the bench and having its inner end 12 turned and pointed to seat in the recessed hub 3. At its other end the stand is hung upon a bent rod 13 having its inner end 1 1 turned upwardly to form a pintle which passes through the openings of ears 15 formed on the back of end piece 2, as shown in Fig. 4:. Near its outer end rod 18 is held by a bracket 16 beyond which it carries an adjustable weight 17 The anchor 11 and rod 13 are so formed and disposed as to support the stand a short distance above the bench to permit of a universal movement of the stand without coming into contact with the bench.

It will be seen from the above description that the stand is supported freely at both ends and that it is capable of swinging laterally as well as vertically about the pointed anchor 11, the parallelism of the end pieces 1 and 2 being maintained at all times through the straps 8, a transverse section through the latter forming an equilateral triangle.

The die plate 3 is of the usual form, having a series of drilled holes 3, and is adapted to be placed in position to utilize any one of the holes for the drawing operation. It is placed in position with one of the holes opposite the opening 5 in end piece 2 and rigidly retained by a stiif spring plate 18 secured to a bracket 19, preferably in the form of a casting having arms 20 rotatably mounted in ears 20 forming part of the end piece. Secured to or formed integral with the swinging bracket 19 is a conical guide 21 adapted to enter the holes of the die plate on the back or entering face of the latter. Any suitable means may be employed to secure the clamp plate 18 in position. For

The end that purpose I have shown a spring arm 22 fastened to end piece 2, bent as shown in Fig. 2 and formed at its outer end with ratchet teeth 23 to engage the wall of an opening 2 1 in the upper end of plate 18. By depressing the free end of arm 22 clamp plate 18 may be swung outwardly to release the die plate. Then looked as shown in Fig. 2, the die plate will be rigidly held against any movement relatively to the stand.

In order to properly aline the stand and die plate after the former has been clamped in position I provide a carrier .25 supported freely in one end of a curved arm 26 adapted to be moved vertically between clamp plates 27, and in a horizontal direction through a clamping device 28. The plates 27 are supported on a threaded rod 29, secured to end piece 2, said rod carrying a nut 30 by which the outer plate 27 may be moved to clamp or release arm 26. The clamp 28 is also supported upon end piece 2 and is of known form as shown in Fig. 1. The curved arm 26 is struck on an are from the center of a given die hole when the die plate is in position, and by the means described the carrier 25 may be adjusted to any desired position so as to be in axial alinement with a given hole of the die plate. As an additional guide for the wire as it emerges from the die plate, I provide a curved arm 31 to which the carrier 25 is rigidly secured, said arm having its inner end of tubular form and resting freely in the opening 5 of end piece 2 and abutting against the front of the die plate, as shown in Fig. 2. The carrier 25 may be placed as far as practicable from the die plate, it being obvious that the farther it is away the more sensitive will be its action on the stand and die plate.

The operation of the device is as follows. The die plate is first placed with one of its holes opposite the opening 5 and then clamped in position by moving plate 18 to cause the guide 21 to enter the back of the hole. Plate 18 is then locked by arm 22. The operator then runs a long straight needle, called a set, through the die hole and the tubular extension of the swinging arm 31. Carrier 25 is then adjusted either vertically or horizontally or both, as may be necessary, to enable the set to pass through it without deflect-ion. When so adjusted, the carrier is clamped securely in place, the result being that the die hole and carrier 25 are in axial alinement. The set is then withdrawn and the end of the reel of wire inserted through the die hole in the usual manner, passing through the tubular extension of arm 31, and carrier 25 to the block where it is fastened. The block is rotated and the drawing proceeded with, the alinement of the die hole and carrier 25 securing the desired position of the die plate to efiect the proper drawing and coiling of the wire at ,the outset of the operation. Shouldthe axis of the die hole and carrier 25 notbe in. aline inent with a given point on the block when the wire is fastened to the latter, slight [rotation'of the block will swing into and ing operation. Any deflection of the axis of the diehole is prevented, during the draw- "ing "operation, by the wire acting on the carrier 25. I thus dispense with the manipulation of the die plate as now customary with the fixed stand and am enabled to cast the wire properly on the init1al rotation of the block.

ator has to pay no attention to the position By the use of the present stand the oper of thedie plate relatively to the block; that I is, it requires no manipulation of the die plate relatively to the block during the formation of the initial coils on the block. The weightl'? is adjustedon rod 13 to act as a counter-balance for the stand and to relieve the traveling. wire of the weight of the stand; The centers of the recessed boss 1 and the opemng 5111 end piece 2 lie in the I axisoft-he stand sothat free lateral and support for the carrier vertical movements are permitted about the endlof anchor ll to allow of the proper alinement of the die hole and carrier 25 with the block.

In l ig. '5 l have shown a modified form of a a In this form the guide s suitably supported 111 a bracket at theends of two threaded rods 32 placed at right angles to each other and having bearings in a bracket 33 which may be conveniently secured to thecend piece 2. The

movements of rod'32 to properly aline the guide may be effected by nuts 34 held betweenthe fixed bearings of bracket 33, as

I will be readily understood.
